Do mosquitos have Haustellate or Mandibulate mouthparts?
Haustellate.
Mandibulate insects (e.g., grasshoppers, beetles) use toothed jaws for chewing, while haustellate insects (e.g., butterflies, mosquitoes) utilize specialized, spesso straw-like appendages to consume liquids
What is the support force exerted by a surface on an object in contact with it, acting perpendicular to the surface?
Normal Force
Salt water is more or less dense than pure water?
More dense
A knife, door stopper, lots of things work.
A statue of Isaac Newton is stationary at the top of a hill. List the forces acting on it.
What is Normal Force and Gravity Force?
Commensalism is the interaction between two organisms where one benefits from the interaction and the other is not affected by the interaction.
Ex: Barnacles attach to whales to travel and filter food from the water, while the whale remains unaffected.
Type of insect legs that are adapted for running.
What are cursorial legs?
What are the two electromagnetic spectrum ranges that have longer wavelengths than visible light?
a circular, equatorial orbit at an altitude of approximately 35,786 km (22,236 miles) where satellites match Earth's rotation, appearing fixed over a single spot. These satellites revolve eastward every 23 hours, 56 minutes, and 4 seconds, crucial for consistent communications and weather monitoring.

If the distance from the fulcrum to the 3kg block is 6m, then what is the distance from the 2kg block to the fulcrum?
9m
What are the two major components of the Central Nervous System?
The brain and spinal cord.
Hard outer covering on insects that protects & supports them and prevents loss of bodily fluids
What is an exoskeleton?
What is the difference between a rock and a mineral?
Minerals are naturally occurring, inorganic solid substances with a specific chemical composition and ordered atomic structure. Rocks are solid, naturally formed aggregates composed of one or more minerals or mineral-like substances. Minerals are uniform, while rocks are mixtures.
Define potable water treatment.
Potable water treatment transforms raw water into safe drinking water through a multi-stage process involving coagulation, flocculation, sedimentation, filtration, and disinfection. These steps remove contaminants like germs, chemicals, and particulates to meet strict regulatory standards.
A wheel with a grooved rim around which a cord passes. It acts to change the direction of a force applied to the cord. What is this simple machine?
What is a pulley?
What are raptorial insect legs adapted for?
Adapted for catching and holding prey.
A study measures the number of COVID-19 cases in a city on a specific day. What is the type of epidemiologic study?
Cross Sectional. Data is collected at only one moment in time, which is good for calculating prevalence.
What type of rock classification is this?
Sedimentary Rock
SONAR is a technology that is commonly used to map the seafloor by emitting sound (acoustic) waves in the ocean and measuring how long it takes for the waves to return to the detector (after they bounce off the seafloor). Is this active or passive sensing?
Active sensing. Passive sensing is the detection of signal coming from an environment without any input from the device.
Name 3 properties of light.
3 of the following: reflection, refraction, dispersion, absorption, diffraction, and polarization
Nathaniel hit his head in a bike collision. He has trouble comprehending speech, retaining memory, and regulating his emotions. What part of the brain did he damage?
Temporal lobe
The over-enrichment of water by nutrients, primarily nitrates and phosphates, leading to excessive algal blooms and severe oxygen depletion that kill aquatic life.
What is eutrophication?
layered, banded, or striped appearance in a metamorphic rock. This texture develops when intense heat/direct pressure (called differential stress) deep within the Earth cause minerals to recrystallize and flatten.
Foliated or foliation.
Describe the difference between the public health approach and clinical approach.
The public health approach focuses on preventing disease and promoting health across entire populations, using research and policy, while the clinical approach focuses on diagnosing and treating illness in individuals.

A and B are fulcrums.
The distance from B to [6kg] on the right is 2m.
The distance from B to A is 3m.
The horizontal distance from [1kg] to A is 3m.
Find the value of x and the horizontal distance from [(x)kg] to A.
x is 3kg since the weight of the upper lever has to be 4kg to balance out the bottom lever.
Distance from [3kg] to A is 1m as 1*3=3*1.
